Phishers have found a way to downgrade—not bypass—FIDO MFA

Researchers recently reported encountering a phishing attack in the wild that bypasses a multifactor authentication scheme based on FIDO (Fast Identity Online), the industry-wide standard being adopted by thousands of sites and enterprises. If true, the attack, reported in a blog post Thursday by security firm Expel, would be huge news, since FIDO is widely regarded as being immune to credential phishing attacks. After analyzing the Expel write-up, I’m confident that the attack doesn’t bypass F

Making a StringBuffer in C, and questioning my sanity

I've been writing a lot of C. Whilst doing so I have been questioning my sanity. Am I an awful programmer? You know what, I think I might be. Kudos to all those devs that created monumental feats with C. Because it is not an easy tool to use. That said, I do enjoy writing C, just as long as I don't have a deadline or any business critical software to deliver. But when I say enjoy, I mean enjoyment in the sense of using a sycthe to cut a lawn, whilst my lawnmower watches on. It's lovely using th

How I keep up with AI progress

Last Updated: 30th June 2025 Generative AI has been the fastest moving technology I have seen in my lifetime. Its also happens to be terribly misunderstood. We have already seen large companies and even governments ship dysfunctional or even dangerous AI products. Sufficiently uninformed people misunderstand how to apply AI with concretely negative consequences. The most common errors of misunderstanding are either underestimation (“it’s all hype that will blow over”) or overestimation (“I do

This Simple Strategy Could Curb One of Semaglutide’s Worst Side Effects

Semaglutide’s ability to help people lose weight is legendary, but so are the side effects. The active ingredient in medications Wegovy and Ozempic, semaglutide is renowned for causing severe nausea in some people, sometimes to the extent that they stop treatment. But new research published in the journal Diabetes Care suggests there may be a simple way to combat that effect. Led by a team in Israel, the researchers found that giving people more time and flexibility to ramp up to the recommende

How to Get Foreign Keys Horribly Wrong

Constraints keep the integrity of your system and prevent you from shooting yourself in the foot. Foreign keys are a special type of constraint because, unlike unique, check, and primary keys, they span more than one relation. This makes foreign keys harder to enforce and harder to get right. In this article, I demonstrate common pitfalls, potential optimizations, and implicit behavior related to foreign keys. Table of Contents Watch 📺 This article is inspired by a talk I gave at DjangoCon EU

Exposed MCP servers across the internet

Knostic’s research team conducted a systematic study to locate exposed MCP servers on the internet. Leveraging Shodan and custom Python tools, we fingerprinted and mapped production MCP servers. All servers we discovered were insecure and revealed their capabilities to anyone asking. In this series of posts, we are sharing our findings, along with a guide detailing how we fingerprinted MCP servers. We identified a total of 1,862 MCP servers exposed to the internet. From this set, we manually v

We Consulted Fitness Experts to Learn the Truth About Vibration Plates for Weight Loss

Step aside mom jeans, scrunchies and denim on denim, there's another trend making a comeback. Vibration plates are trending once again. Similar to the mid-20th-century vibrating belt machines, vibration plates have been said to provide the body with various benefits and can even be a tool for weight loss. But is the hype backed by science and expert opinions, or is it all social media hearsay? To find out if you should add a vibration plate to your workout routine, we asked personal trainers an

Why is AI so slow to spread?

T alk to executives and before long they will rhapsodise about all the wonderful ways in which their business is using artificial intelligence. Jamie Dimon of JPMorgan Chase recently said that his bank has 450 use cases for the technology. “ AI will become the new operating system of restaurants,” according to Yum! Brands, which runs KFC and Taco Bell. AI will “play an important role in improving the traveller experience”, says the owner of Booking.com. In the first quarter of this year executiv

Perplexity sees India as a shortcut in its race against OpenAI

While OpenAI has cemented its lead in the U.S., Perplexity is taking a different route — quietly expanding into India to compete in the next phase of AI adoption. The search-focused AI startup is rapidly adding millions of users in the world’s second-largest internet and smartphone market, positioning itself for mass-market scale.

Citrix Bleed 2 exploited weeks before PoCs as Citrix denied attacks

A critical Citrix NetScaler vulnerability, tracked as CVE-2025-5777 and dubbed "CitrixBleed 2," was actively exploited nearly two weeks before proof-of-concept (PoC) exploits were made public, despite Citrix stating that there was no evidence of attacks. GreyNoise has confirmed its honeypots detected targeted exploitation from IP addresses located in China on June 23, 2025. "GreyNoise has observed active exploitation attempts against CVE-2025-5777 (CitrixBleed 2), a memory overread vulnerabili

Running TypeScript Natively in Node.js

Since v23.6.0, Node.js enables "type stripping" by default. If you are using v23.6.0 or later and your source code contains only erasable typescript syntax, you do not need this article. Since V22.6.0, Node.js has experimental support for some TypeScript syntax via "type stripping". You can write code that's valid TypeScript directly in Node.js without the need to transpile it first. The --experimental-strip-types flag tells Node.js to strip the type annotations from the TypeScript code before

Tell HN: Notion Desktop is monitoring your audio and network

If you have the Notion Desktop App installed, you may have started to notice a "In a meeting? Start AI Meeting Notes" notification pop up exactly when you are joining a virtual meeting (e.g. joining a Google Meet on Firefox). At first, I assumed it must have been using my Google Workspace account to snoop on my calendar. But then I started to notice it would notify exactly when I joined even if I was late and the meeting had previously started. This was the response from Notion Support after t

Samsung DeX turns the Galaxy Z Flip 7 into a pocket-sized PC, but it’s missing one key feature

TL;DR The new Galaxy Z Flip 7 is the first in Samsung’s clamshell foldable lineup to support Samsung DeX, turning it into a compact, portable PC. DeX provides a full desktop experience on an external monitor and works with a wired connection, even when the phone is closed. While a powerful addition, it lacks the ability to use the cover screen as a touchpad, a feature found on competing Razr phones. Samsung’s clamshell folding phones have always been true flagships in terms of specs and perfo

I love anti-reflective displays, but an iPhone one is no big deal

A report yesterday suggested that the two iPhone 17 Pro models could get an anti-reflective display, after Apple’s suppliers managed to overcome production difficulties. I do love anti-reflective displays, and still have very fond memories of my all-time favorite Apple one from way back in 2004, but an iPhone one would have only moderate appeal to me … There was a time when all screens were matte. Then along came glossy screens, Apple and the rest of the tech industry fell in love with them, a

Zuckerberg and Meta investors reach settlement in $8B privacy case

In Brief Mark Zuckerberg and other current and former Meta executives have settled a lawsuit filed by a group of shareholders. They were seeking $8 billion for the damage the executives caused the company by allowing repeated violations of Facebook users’ privacy in relation to the Cambridge Analytica scandal.

Beeper Relaunch Lets You Link Your Chat Apps Without the Cloud, but Still No iMessage

Beeper, which was once known for attempting to provide access to the iMessage network on non-Apple devices, is relaunching itself Wednesday with a continued focus on being a texting hub for bringing together conversations from many other services. This app first launched last year after the company was acquired by Automattic and was merged with the similar Texts.com service. The biggest difference with the new launch is that Beeper is adding the ability to link your chat apps together using jus
